Using data from The Australian Paediatric Exposure to Radiation Cohort (Aust-PERC) study, this doctoral research aims to explore the relationship between low-dose radiation exposed from CT scans and site-specific solid cancers.

Computed Tomography (CT) scans use multiple X-rays to support modern diagnosis or treatment. Such medical X-rays deliver ionizing radiation which has enough energy to penetrate the whole body. It is concerned that the adverse effect after ionizing radiation exposure, however, cancer risks following low radiation doses from diagnostic CT scans are poorly understood.

By using data from The Australian Paediatric Exposure to Radiation Cohort study (Aust-PERC), including almost 1 million CT scans from over 11 million young Australians and with estimated radiation doses delivered to 32 different target organs, this thesis aims to relate solid cancer risks to radiation dose in the relevant organ, to age at exposure and time since exposure.
